In terms of data amplification and maintenance, in this year, we’ve maintained 46 systems under continuous running, registered 994 ChemiCloud accounts, monitored 5 systems running, and expanded access to 6 data sources. We’ve developed vendor’s data integration programs and integrated 10,723 chemical substances and 14,005 vendor data. Through data cleaning, information logic and manual judgment of normalization, the available normalizing grade of chemical substances and vendor names can be upgraded to 69% and 85%, respectively.
In terms of the development and interface of department requirements, we’ve totally developed and refined 12 main functions, including: web page revision, built 5 application theme zones, simplified the browsing effect of handheld devices, developed the disclosure of operating information on chemical substances, integrated disaster prevention information and expanded two data sources, providing notification materials for the toxic chemical substance permission management system and factory hazardous materials declaration network information, two web service functions are applicable for department interface.
In terms of big data analysis, this plan introduces data analysis technology on mega data and AI technology; use ChemiCloud to integrate the existing data and external data of various departments; and has completes the development and construction of four big data analysis functions. In vendor risk analysis, the Bayesian network analysis method is used to build a prediction model, provide a list of referenced risky vendors for the business audit entity to reduce the audit labor, time and expenses. In the chemical substance industry association analysis, combine ChemiCloud and electronics invoice transaction data; use social network analysis method, carried out the food safety operation; made 37 suggestions on food safety in-priority management and conduct 57 food safety risk suspected chemical substances for transaction flow analysis with the Middle Office of MOEA. When the vendor amount involved in the trading network is enormous, it is practically difficult to quickly master the trading relationship through visualization; it must use social networks to calculate the centralities, realize vendor’s transaction relationship, or which vendor is taking the gatekeeper role, communications among vendors are achieved through that gatekeeper vendor to complete the transaction; which helps to quickly master various key vendors in a complex network.
For related domestic and foreign chemical substances news and websites, since May 2018, about 10,121 domestic news and 5,743 foreign warnings have been collected for analysis. We use text exploration and document topics classification to identify the attributes and topics of news and to master the core of current affairs issues.
Regarding the feasibility of promoting electronic invoices in stages, we evaluate and plan for the tasks from the aspects of laws / regulations, vendors and management effectiveness; propose possible problems and respective solutions; propose application scenarios based on fiscal and taxation data for toxicant management, and provide a reference for decision making of ChemiCloud for toxicant and chemical source management, flow tracking, and cross-checking.
In the single service window of chemical substances, we analyzed the laws / regulations of various departments, compare the overlapping chemical substances and columns of each system, set forth 9 suggested trial agency systems; and proposed two implementation methods per the committee members’ opinions, which are the integration of application information and the single service interface as a reference for future implementation.
At present, the analysis of warning factors for dangerous articles operating vendors has now completed the collection of warning analysis factors for 603 dangerous articles and nearly 7,000 vendors. According to the analysis factors, the calculation method of warning scores for dangerous articles and vendors has been drawn up. A priority list of dangerous articles and vendors' warnings is produced for the firefighting entities to refer thereof.
